The "No Man's Sky" release date for the PS4 has been reportedly set to August 2015 while the "No Man's Sky" release date for the PC is reportedly going to be on 2016.
Cyberland has reported that Hello Games allegedly set the "No Man's Sky" release date for the PS4 on August 2015 and the PC version would be released on 2016. The report also notes that gamers should expect new footage and details of the game to be revealed on GDC 2015.
"My contact over at Hello Games told me that they are planning to release the game on August for the PS4, just after E3. Expect new gameplay videos and a lot more stuff that's going to be announced at GDC. PC release is going to be on 2016" as was noted on the report.
As to why the PC version would be released after the PS4 version of "No Man's Sky", Gamespot reported that Hello Games confirmed that "No Man's Sky" is going to be a timed exclusive for the PS4.
"Now we know that No Man's Sky will, in fact, launch on PC--although not right away. In the September issue of Edge, the game is confirmed to be a timed PS4 exclusive and will be released on computers at a later date" as was noted on the report.
Gamespot also quotes Hello Games' Sean Murray about the PS4 and PC release of "No Man's Sky":
"I actually got in a bit of trouble for saying that we wanted the game to feel really 'console-y'. We've always had PC in mind but in my head [console-y] means solid framerate and immediate controls. I think a PC game can be 'console-y' and it's intended as a compliment, but I get in trouble for saying it."
